Language differences between institutionalized and noninstitutionalized retarded children.

The linguistic performances of 15 noninstitutionalized and 15 institutionalized retarded children were compared on usage of grammatical categories and structure of spoken language (Length--Complexity Index) and for underlying subskills (Illinois Test of Psycholinguistic Abilities). Differences were not found between the groups for usage of grammatical categories or structures but were found for subskills of Auditory Reception. Auditory Sequential Memory, Verbal Expression, and Auditory Closure. Further analysis by multiple stepwise regression indicated that noninstitutionalized and institutionalized retarded children may be differentiated by examining a number of linguistic variables. The grammatical structure of language appeared less affected by environment than were the semantic and auditory elements.

Oral sensory and motor behaviors of children with /s/ or /r/ misarticulations.

Measurements of lingual two-point discrimination, oral form discrimination, and alternate motion rate of the tongue were made in 15 children who had normal articulation, 15 children who misarticulated /s/, and 15 children who misarticulated /r/. The two groups of children with misarticulations were found to differ from each other as well as from normal children on various aspects of oral sensation and motor abilities. These findings are interpreted as evidence for the existence of different bases for the misarticulations of the two disordered groups.

Asymmetry in two-point discrimination on the tongues of adults and children.

Previous studies have shown that some adults have better discrimination for two-point perception on one side of the tongue than on the other. This has been referred to as asymmetry in lingual two-point discrimination. No data are available regarding lingual asymmetries in children. As perceptual differences frequently occur between children and adults, lingual two-point discrimination was measured in children and in adults. Whereas all children showed symmetrical patterns of lingual two-point discrimination, 8 of 15 adults showed asymmetrical patterns. Differences between adults and children appear to be related to the development of the central nervous system rather than to the change in peripheral sensory mechanisms.
